TECHNICAL FIELD

The present disclosure relates to, but is not limited to, a field ofwireless communications and, in particular, to a wireless resourceconfiguration method and device.

BACKGROUND

Machine to Machine (M2M) communications are an important subject in 5thgeneration (5G) mobile communication technologies and an importantapplication of wireless communications in the future. In the M2Mcommunications, a research sub-topic of NarrowBand-Internet of Things(NB-IoT) has been proposed for a terminal featured with low costs andlow throughput. That is, a low-throughput wireless communication serviceis provided for low-cost user equipment (UE) in the NB-IoT within a 200kHz spectral bandwidth.

A series of parameters are configured for the conventional NB-IoTterminal to support communications of the NB-IoT terminal in a NB-IoTsystem. However, considering factors existing in the M2M applicationfield of the NB-IoT, such as limitation to the shape of the battery(e.g., button battery) used in the terminal, and electric capacity ofthe terminal is limited. A such terminal has a low transmitting powerand a poor uplink coverage, and can be called low power class UE. Ifparameters used for the conventional UE are still configured for the lowpower class UE, the low-power-class UE may not access the network orcommunicate normally.

Therefore, after the low power class UE is introduced in the NB-IoTsystem, how to configure corresponding wireless resources becomes anurgent problem to be solved in the NB-IoT system.

DETAILED DESCRIPTION

Technical solutions in embodiments of the present disclosure will bedescribed clearly and completely in conjunction with drawings in theembodiments of the present disclosure.

In a NB-IoT system, the maximum transmit power of a conventional NB-IoTterminal is 20 dBm or 23 dBm. A UE maximum transmit power is representedby a UE power class. For example, The UE maximum transmit power is 20dBm, corresponding to UE power class 3; and the UE maximum transmitpower is 23 dBm, corresponding to UE power class 5. In the M2Mapplication field of the NB-IoT, the UE maximum transmit power may be aslow as 14 dbm. It is necessary to configure corresponding parameters forlow power class UE to enable the low power class UE to be accessed thenetwork.

An uplink maximum coverage range of the low power class UE is less thana maximum coverage range of high power class UE. In a multiband network,the lower the frequency is, the larger the wireless coverage range is.Therefore, to solve the problem of insufficient coverage of the lowpower class UE, in the multiband network, how to carry the low powerclass UE on a low frequency band is a problem that needs to be solvedafter introducing the low power class UE. And the distribution of the UEin a cell is implemented by the function of cell selection andreselection. A cell selection and reselection parameter currently cannotdistinguish the UE power class. Therefore, the current strategy cannotdifferentially select the frequency band carried by the UE according tothe UE power class.

In addition, the NB-IoT system supports coverage enhancement. That is,when the wireless coverage is poor, the receiving reliability of areceiving end is ensured by a repetition transmission of a physicallayer of a transmitting end. The larger the number of repetitions is,the greater the receiving reliability is. In addition, the receivingreliability is also related to an emission power. Under a samecondition, the larger the UE emission power is, the greater thereceiving reliability of an Evolved Node B (eNodeB) is. So, for the UEwith different power class, the requirement for the number of physicallayer repetitions is different. In the NB-IoT system, the currentwireless coverage level threshold (a reference signal receiving power(RSRP) threshold) is set in units of cells, and is configured to the UEby a broadcast message. For an initial PRACH process, a wirelesscoverage level of the UE is obtained by a comparison between a wirelessmeasuring RSRP value and the RSRP threshold. And for the PRACH processtriggered by a physical downlink control channel (PDCCH) order, thewireless coverage level of the UE is indicated by PDCCH downlink controlinformation (DCI). The number of physical layer repetitions of the PRACHand PRACH resource information is configured to the UE at thegranularity of the wireless coverage level by the broadcast message. TheUE and eNodeB need to transmit and receive PRACH information accordingto a PRACH parameter carried in the broadcast message corresponding tothe wireless coverage level. However, when receiving the

PRACH information, the eNodeB does not know an emission power class ofthe UE. If the eNodeB just corresponds to the number of physical layerrepetitions of the PRACH by simply differentiating different UE powerclass, the eNodeB does not know the PRACH transmitted by which UE powerclass when receiving the PRACH information, thus the eNodeB cannotnormally parse the PRACH information. Therefore, the number of physicallayer repetitions of the PRACH cannot be currently configured for the UEpower class.

In summary, after the NB-IoT system introduces the low power class UE,various problems occur. To enable the low power class UE to communicatenormally, the embodiments of the present disclosure provide a wirelessresource configuration method and device for solving the above problems.

In step S201: a base station broadcasts first access parameterinformation. The first access parameter information includes a minimumquality threshold configured to initiate a PRACH process and configuredfor UE power class.

In step S202, the UE determines, according to the UE power class, theminimum quality threshold configured to initiate the PRACH process.

In step S203, the UE determines whether a cell quality is currentlygreater than or equal to the minimum quality threshold configured toinitiate the PRACH process.

In step S204, if the cell quality is currently greater than or equal tothe minimum quality threshold configured to initiate the PRACH process,the UE is capable of initiating the PRACH, otherwise, the UE isincapable of initiating the PRACH.

Since an uplink transmit power of the low power class UE is low, and theUE may be accessed and resided at the cell provided by the base station,but when the UE is performing the PRACH process, if the cell quality ispoor, the interference on an uplink signal transmitted by the UE issevere, and the PRACH process may fail due to low uplink transmit power.Therefore, the base station may include, in the transmitted first accessparameter information, the minimum quality threshold configured toinitiate the PRACH process and configured for UE power class, that is, aminimum cell quality threshold capable of supporting the UE to initiatethe PRACH process configured to different UE power classes. Afterreceiving the first access parameter information broadcast by the basestation, the UE may determine, according to its own UE power class, theminimum quality threshold configured to initiate the PRACH process.Then, the UE determines the relationship between the quality of the cellthe UE currently resides and the minimum quality threshold configured toinitiate the PRACH process. If the cell quality is currently greaterthan or equal to the minimum quality threshold configured to initiatethe PRACH process, the UE is capable of initiating the PRACH, otherwise,the UE is incapable of initiating the PRACH.

Moreover, when the UE does not receive any parameter configured for UEpower class, the UE determines whether the cell quality is currentlygreater than or equal to a preset default value corresponding to theminimum quality threshold applicable to initiate the PRACH process. Ifthe cell quality is currently greater than or equal to the presetdefault value, the UE is capable of initiating the PRACH, otherwise, theUE is incapable of initiating the PRACH. It is to be noted that, thepreset default value corresponding to the minimum quality thresholdconfigured to initiate the PRACH process may be a default value definedby standards, which may avoid a case in which the PRACH processperformed by the low power class fails due to poor cell quality when theUE does not receive any parameter configured for UE power class, therebysaving the wireless resources.

Moreover, in an exemplary implementation mode, a minimum qualitythreshold applicable to initiate a PRACH process may be defined onlyaccording to a cell not supporting low power class UE signaling, and theminimum quality threshold applicable to initiate the PRACH process is apredefined default value.

For the cell not supporting low power class UE signaling, the method ofthe present disclosure may further include:

the low power class UE determines the cell quality is currently greaterthan or equal to the minimum quality threshold of the cell notsupporting low power class UE signaling to initiate the PRACH process,if yes, the UE is capable of initiating the PRACH, otherwise, the UE isincapable of initiating the PRACH;

the cell not supporting low power class UE signaling is determinedaccording to whether a parameter or an indication for configuring thelow power class UE is included in a cell broadcast, if no parameter orindication for configuring the low power class UE is included in thecell broadcast, the UE confirms the cell as the cell not supporting lowpower class UE.

For the above exemplary implementation mode, FIG. 3 shows an exemplaryof triggering the PRACH process by the low power class UE when the cellnot supporting low power class UE signaling has predefined the minimumquality threshold applicable to the low power class UE to initiate thePRACH process. In FIG. 3, the minimum quality threshold applicable toinitiate the PRACH process uses at least one of RSRP threshold or RSRQthreshold as an example, and the steps included may be described below.

In step S301, the cell not supporting low power class UE signaling haspredefined at least one of the minimum quality RSRP threshold or theminimum quality RSRQ threshold applicable to initiate the PRACH process.

In step S302: the low power class UE triggers the PRACH process.

In step S303: the low power class UE determines whether the cellsupports low power class UE signaling. If yes, the process goes intoS304. If not, the process goes into S305.

It is to be noted that the cell not supporting low power class UEsignaling may be determined based on whether the relevant parameter orindication of the low power class UE is included in the cell broadcast.If no parameter for configuring the low power class UE is included inthe cell broadcast, the UE determines that the cell is the cell notsupporting low power class UE signaling.

In step S304, the UE determines whether the cell quality is currentlygreater than or equal to the minimum quality RSRP/RSRQ threshold of thelow power class UE predefined by standards to initiate the PRACHprocess. If yes, the process goes into S305. If not, the process goesinto S306.

In step S305: the UE is capable of initiating the PRACH process at thecell.

In step S306: the UE is incapable of initiating the PRACH process at thecell.

Moreover, in an exemplary implementation mode, at least one of RSRPthreshold or

RSRQ threshold of the low power class UE to access the cell is defined asystem broadcast message, and then the low power class UE performs cellselection and reselection, which may include at least one of thefollowing:

the low power class UE determines whether the cell quality is currentlygreater than or equal to the RSRP threshold of the low power class UE toaccess the cell; if the cell quality is currently greater than or equalto the RSRP threshold of the low power class UE to access the cell, thelow power class UE determines, according to the S criterion selected bya current cell, whether the current cell fulfills the camp condition;otherwise, the low power class UE reduces a reselection priority of thecurrent cell or determine the current cell is unacceptable for camping;

the low power class UE determines whether the cell quality is currentlygreater than or equal to the RSRQ threshold of the low power class UE toaccess the cell; if the cell quality currently is greater than or equalto the RSRQ threshold of the low power class UE to access the cell, thelow power class UE determines, according to the S criterion selected bythe current cell, whether the current cell fulfills the camp condition;otherwise, the low power class UE reduces the reselection priority ofthe current cell or confirm the current cell is unacceptable forcamping; and

the low power class UE determines whether the cell quality is currentlygreater than or equal to the RSRP threshold and the RSRQ threshold ofthe low power class UE to access the cell; if the cell quality iscurrently greater than or equal to the RSRP threshold and the RSRQthreshold of the low power class UE to access the cell, the low powerclass UE determines, according to the S criterion selected by thecurrent cell, whether the current cell fulfills the camp condition;otherwise, the low power class UE reduces the reselection priority ofthe current cell or confirm the current cell is unacceptable forcamping.

It is to be noted that the step in which the low power class UE reducesthe reselection priority of the current cell may include at least one ofthe following:

the low power class UE firstly selects a cell in which the cell qualityis greater than or equal to the RSRP threshold of the low power class UEto access the cell to reside; if there is no other cells in which thecell quality is greater than or equal to the RSRP threshold of the lowpower class UE to access the cell, the cell in which the cell quality isless than the RSRP threshold of the low power class UE to access thecell is selected to reside;

the low power class UE firstly selects the cell in which the cellquality is greater than or equal to the RSRQ threshold of the low powerclass UE to access the cell to reside; if there is no other cells inwhich the cell quality is greater than or equal to the RSRQ threshold ofthe low power class UE to access the cell, the cell in which the cellquality is less than the RSRQ threshold of the low power class UE toaccess the cell is selected to reside; or

the low power class UE firstly selects the cell in which the cellquality is greater than or equal to the RSRP threshold and the RSRQthreshold of the low power class UE to access the cell to reside; ifthere is no other cells in which the cell quality is greater than orequal to the RSRP threshold and the RSRQ threshold of the low powerclass UE to access the cell, the cell in which the cell quality is lessthan the RSRP threshold or the RSRQ threshold of the low power class UEto access the cell is selected to reside.

Correspondingly, the low power class UE confirms the current cell isunacceptable for camping, which includes: the low power class UEconfirms the current cell is in an access barred status, and the currentcell is excluded when the cell selection and reselection.

It is to be noted that when the UE does not receive at least oneparameter of the RSRP threshold and the RSRQ threshold of the low powerclass UE to access the cell, at least one of the RSRP threshold or theRSRQ threshold of the low power class UE to access the cell is apredefined default value.

For this implementation mode, FIG. 4 shows a process of cell selectionand reselection of the low power class UE. The steps included aredescribed below.

In step 401: the system broadcast message defines at least one of RSRPthreshold or RSRQ threshold applicable to access the cell of the lowpower class UE and predefines a default value of the threshold.

In step 402: the low power class UE performs the cell selection andreselection.

In step 403: the low power class UE determines whether at least one ofthe RSRP threshold or the RSRQ threshold of the low power class UE toaccess the cell is included in the cell broadcast. If yes, the processgoes into S404. If not, the process goes into S405.

In step S404: the UE determines whether the cell quality is currentlygreater than or equal to the RSRP threshold, or the RSRQ threshold, orthe RSRP threshold and the RSRQ threshold of the low power class UE toaccess the cell. If yes, the process goes into S406. If not, the processgoes into S407. For example, when the low power class UE determines theRSRP threshold of the low power class UE to access the cell is includedin the cell broadcast, the UE determines whether the cell quality iscurrently greater than or equal to the RSRP threshold of the low powerclass UE to access the cell. If yes, the process goes into S406. If not,the process goes into S407. When the low power class UE determines theRSRQ threshold of the low power class UE to access the cell is includedin the cell broadcast, the UE determines whether the cell quality iscurrently greater than or equal to the RSRQ threshold of the low powerclass UE to access the cell. If yes, the process goes into S406. If not,the process goes into S407. When the low power class UE determines theRSRP threshold and the RSRQ threshold of the low power class UE toaccess the cell are included in the cell broadcast, the UE determineswhether the cell quality is currently greater than or equal to the RSRPthreshold and the RSRQ threshold of the low power class UE to access thecell. If yes, the process goes into S406. If not, the process goes intoS407.

In step S405: the UE determines whether the cell quality is greater thanor equal to the default value of the RSRP threshold, or the defaultvalue of the RSRQ threshold, or the default value of the RSRP thresholdand the RSRQ threshold predefined by the standards of the low powerclass UE to access the cell. If yes, the process goes into S406. If not,the process goes into S407. For example, the UE determines whether thecell quality is greater than or equal to the default value of the RSRPthreshold predefined by the standards of the low power class UE toaccess the cell. If yes, the process goes into S406. If not, the processgoes into S407. Or the UE determines whether the cell quality is greaterthan or equal to the default value of the RSRQ threshold predefined bythe standards of the low power class UE to access the cell. If yes, theprocess goes into S406. If not, the process goes into S407. Or UEdetermines whether the cell quality is greater than or equal to thedefault value of the RSRP threshold and the RSRQ threshold predefined bythe standards of the low power class UE to access the cell. If yes, theprocess goes into S406. If not, the process goes into S407.

In step S406: the UE determines whether the cell fulfills the campcondition according to the S criterion selected by the cell.

In step S407: the UE reduces a cell selection priority of the cell orconfirms the cell is unacceptable for camping.

The step in which the UE reduces the cell selection priority of the cellmay includes at least one of:

the low power class UE preferably selects the cell in which the cellquality is greater than or equal to the RSRP threshold of the low powerclass UE to access the cell to reside; only when there is no other cellsin which the cell quality is greater than or equal to the RSRP thresholdof the low power class UE to access the cell, the cell in which the cellquality is less than the RSRP threshold of the low power class UE toaccess the cell is selected to reside;

the low power class UE preferably selects the cell in which the cellquality is greater than or equal to the RSRQ threshold of the low powerclass UE to access the cell to reside; only when there is no other cellsin which the cell quality is greater than or equal to the RSRQ thresholdof the low power class UE to access the cell, the cell in which the cellquality is less than the RSRQ threshold of the low power class UE toaccess the cell is selected to reside; or

the low power class UE preferably selects the cell in which the cellquality is greater than or equal to the RSRP threshold and the RSRQthreshold of the low power class UE to access the cell to reside; onlywhen there is no other cells in which the cell quality is greater thanor equal to the RSRP threshold and the RSRQ threshold of the low powerclass UE to access the cell, the cell in which the cell quality is lessthan the RSRP threshold or the RSRQ threshold of the low power class UEto access the cell is selected to reside.

The step in which the low power class UE confirms the cell isunacceptable for camping may be: the low power class UE believes thatthe cell is in a state which equals to Barred. The UE directly excludesthe cell when cell selects and reselects.

Moreover, in an exemplary implementation mode, when communicationstandards have predefined at least one of RSRP threshold or RSRQthreshold of the low power class UE to access the cell for s cell notsupporting the low power class UE signaling, the low power class UEperforms the cell selection and reselection. It is to be noted that theat least one of the RSRP threshold or the RSRQ threshold of the lowpower class UE to access the cell is defined only according to the cellnot supporting the low power class UE signaling, and the at least one ofthe RSRP threshold or the RSRQ threshold of the low power class UE toaccess the cell is a predefined default value.

The method may also include at least one of the following:

for the cell not supporting the low power class UE signaling, the lowpower class UE determines whether the cell quality is currently greaterthan or equal to a predefined value of the RSRP threshold of the lowpower class UE to access the cell, if the cell quality is currentlygreater than or equal to the predefined value of the RSRP threshold ofthe low power class UE to access the cell, the low power class UEdetermines, according to the S criterion for cell selection whether thecurrent cell fulfills the camp condition; otherwise, the low power classUE reduces the selection priority of the current cell or confirm thecurrent cell is unacceptable for camping;

for the cell not supporting the low power class UE signaling, the lowpower class UE determines whether the cell quality is currently greaterthan or equal to the predefined value of the RSRP threshold and the RSRQthreshold of the low power class UE to access the cell; if the cellquality is currently greater than or equal to the predefined value ofthe RSRP threshold and the RSRQ threshold of the low power class UE toaccess the cell, the low power class UE determines, according to the Scriterion for cell selection whether the current cell fulfills the campcondition; otherwise, the low power class UE reduces the selectionpriority of the current cell or confirm the current cell is unacceptablefor camping.

It is to be noted that the method may also include:

The cell not supporting low power class UE signaling is determinedaccording to whether a parameter or an indication for configuring thelow power class UE is included in a cell broadcast. If no parameter orindication for configuring the low power class UE is included in thecell broadcast, the UE confirms the cell as the cell not supporting lowpower class UE.

FIG. 5 shows a process of cell selection and reselection of another lowpower class UE. The steps included may be described below.

In step S501: standards have predefined at least one of RSRP thresholdor RSRQ threshold of the low power class UE to access the cell for acell not supporting low power class UE.

In step S502: the low power class UE performs the cell selection andreselection.

In step S503: the low power class UE determines whether the cellsupports low power class UE signaling. If yes, the process goes intoS504. If not, the process goes into S505.

It is to be noted that the cell not supporting low power class UEsignaling may be determined based on whether the relevant parameter orindication of the low power class UE is included in the cell broadcast.If no parameter for configuring the low power class UE is included inthe cell broadcast, the UE determines that the cell is the cell notsupporting low power class UE signaling.

In step S504: the UE determines whether the cell quality is currentlygreater than or equal to the RSRP threshold, or the RSRQ threshold, orthe RSRP threshold and the RSRQ threshold of the low power class UEdefined by the standards to access the cell. If yes, the process goesinto S505. If not, the process goes into S506. For example, if thestandards have predefined the RSRP threshold of the low power class UEto access the cell for the cell not supporting low power class UE, theUE determines whether the cell quality is currently greater than orequal to the RSRP threshold predefined by the standards of the low powerclass UE to access the cell. If yes, the process goes into S505. If not,the process goes into S506. If the standards have predefined the RSRQthreshold of the low power class UE to access the cell for the cell notsupporting low power class UE, the UE determines whether the cellquality is currently greater than or equal to the RSRQ thresholdpredefined by the standards of the low power class UE to access thecell. If yes, the process goes into S505. If not, the process goes intoS506. If the standards have predefined the RSRP threshold and the RSRQthreshold of the low power class UE to access the cell for the cell notsupporting low power class UE, the UE determines whether the cellquality is currently greater than or equal to the RSRP threshold and theRSRQ threshold predefined by the standards of the low power class UE toaccess the cell. If yes, the process goes into S505. If not, the processgoes into S506.

In step S505: the UE determines whether the cell fulfills the campcondition according to the S criterion selected by the cell.

In step S506: the UE reduces a cell selection priority of the cell orconfirms the cell is unacceptable for camping.

The step in which the UE reduces the cell selection priority of the cellmay include at least one of:

the low power class UE preferably selects the cell in which the cellquality is greater than or equal to the RSRP threshold of the low powerclass UE to access the cell to reside; only when there is no other cellsin which the cell quality is greater than or equal to the RSRP thresholdof the low power class UE to access the cell, the cell in which the cellquality is less than the RSRP threshold of the low power class UE toaccess the cell is selected;

the low power class UE preferably selects the cell in which the cellquality is greater than or equal to the RSRQ threshold of the low powerclass UE to access the cell to reside; only when there is no other cellsin which the cell quality is greater than or equal to the RSRQ thresholdof the low power class UE to access the cell, the cell in which the cellquality is less than the RSRQ threshold of the low power class UE toaccess the cell is selected to reside; or

the low power class UE preferably selects the cell in which the cellquality is greater than or equal to the RSRP threshold and the RSRQthreshold of the low power class UE to access the cell to reside; onlywhen there is no other cells in which the cell quality is greater thanor equal to the RSRP threshold and the RSRQ threshold of the low powerclass UE to access the cell, the cell in which the cell quality is lessthan the RSRP threshold or the RSRQ threshold of the low power class UEto access the cell is selected to reside.

The step in which the low power class UE confirms the cell isunacceptable for camping may be: the low power class UE believes thatthe cell is in a state which equals to Barred. The UE directly excludesthe cell when cell selects and reselects.

FIG. 6 is a flowchart of a wireless resource configuration methodaccording to embodiment three of the present disclosure. As shown inFIG. 6, the wireless resource configuration method in this embodimentincludes the steps described below.

In step S601: a base station transmits second access parameterinformation to UE. The second access parameter information includes aparameter for enabling the UE to learn a wireless coverage level. Thesecond access parameter information is used for enabling the UE receivedthe second access parameter information to determine the wirelesscoverage level according to a UE power class.

In step S602: the UE determines the wireless coverage level according tothe UE power class and the second access parameter information.

In step S603: the UE determines a resource used for PRACH according tothe wireless coverage level.

Before the UE is accessed the base station and communication by the cellprovided by the base station, used transmission resources need to bedetermined firstly. For the low power class UE, if a resource is usedthe same as the resource used for conventional power class UE, then thetransmission may fail. Therefore, the base station may transmit thesecond access parameter information to the UE. The second accessparameter information includes a parameter for enabling the UE to learnthe wireless coverage level according to the UE power class. Since anuplink transmission power the UE with different UE power class isdifferent, a wireless coverage capability of the UE with different UEpower class is different. The UE with different wireless coveragecapability is differentiated by different wireless coverage level. Thesecond access parameter information may be carried by different message.After receiving the second access parameter information, the UEdetermines, according to its own UE power class, the wireless coveragelevel corresponding to the UE. Then, the UE, according to the determinedwireless coverage level, determines the subsequent communication, thatis, the resource used for the PRACH process.

After transmitting the second access parameter information to the UE,the base station enables the UE received the second access parameterinformation to determine according to its own UE power class, thewireless coverage level, and determine, according to the wirelesscoverage level, the resource used for the PRACH, which enables that thelow power class UE is capable of determining the resource used for thePRACH process in the network and provides the basic guarantee forcommunication in the network for the UE.

FIG. 7 is a flowchart of a wireless resource configuration methodaccording to embodiment four of the present disclosure. As shown in FIG.7, the wireless resource configuration method in this embodimentincludes the steps described below.

In step S701, a base station broadcasts second access parameterinformation. The second access parameter information includes at leastone of: a wireless coverage level threshold, a PRACH parameterconfigured based on a wireless coverage level, or a wireless coveragelevel threshold offset based on a UE power class.

In step S702, the UE determines the wireless coverage level of the UEaccording to the UE power class and the second access parameterinformation.

In step S703, the UE determines, according to the wireless coveragelevel, the resource used for the PRACH.

In step S704, the UE transmits PRACH information on the determinedresource.

In step S705, after receiving the PRACH information, the base stationdetermines, according to the resource occupied by the PRACH information,the wireless coverage level of the UE.

In step S706, the base station determines, according to the wirelesscoverage level of the UE, to transmit a number of physical layerrepetitions of a PDCCH.

Before the UE accesses the cell provided by the base station or residesat the cell provided by the base station, the base station cannot learnthe transmission resource used for communication by the UE, thus it isnecessary to broadcast the second access parameter information. Thesecond access parameter information includes at least one of: thewireless coverage level threshold, the PRACH parameter configured basedon the wireless coverage level, or the wireless coverage level thresholdoffset based on the UE power class. After receiving the second accessparameter information, the UE compares, according to its own UE powerclass and a wireless coverage measurement value, with the wirelesscoverage level threshold, thereby acquiring the wireless coverage levelin which the UE is currently located. After determining the wirelesscoverage level in which the UE is currently located, the UE determinesthe resource used for the PRACH according to the PRACH parameterconfigured based on the wireless coverage level.

After determining the resource used for the PRACH, the UE may use theresource for the PRACH process and transmit PRACH information to thebase station, such as PRACH preamble information in an initial PRACHprocess. After receiving the PRACH information transmitted by the UE,the base station may determine the wireless coverage level of the UEaccording to the resource used by the PRACH information. Since thewireless coverage level of the UE has a corresponding relationship withthe UE power class, after determining the wireless coverage level of theUE, the UE may determine to transmit the number of physical layerrepetitions of the PDCCH. Since the UE with different power class hasdifferent receiving capability, and the receiving capability of the lowpower class UE is poor, therefore, large number of downlink physicallayer repetitions is required for the low power class UE in order toenhance the receiving capability of the UE.

The method of determining, by the UE, according to its own UE powerclass and the second access parameter information, the wireless coveragelevel may be: for the initial PRACH process of conventional power classUE: after receiving a broadcast message, the conventional power class UEacquires a wireless coverage level RSRP threshold [threshold 0,threshold 1]: determining the wireless coverage level by comparing thewireless coverage level RSRP threshold with a RSRP value measuredcurrently; a coverage in which the RSRP value is greater than or equalto the threshold 0 is coverage level 0; a coverage in which the RSRPvalue is less than the threshold 0 and greater than or equal to thethreshold 1 is coverage level 1; and a coverage in which the RSRP valueis less than the threshold 1 is coverage level 2. For the initial PRACHprocess of the low power class UE: after receiving the broadcastmessage, the low power class UE acquires the wireless coverage levelRSRP threshold [threshold 0, threshold 1]: determining the wirelesscoverage level by a high coverage level threshold (the threshold 0) andautomatically reduce one class of the determined wireless coveragelevel: a coverage which is greater than or equal to the threshold 0 isthe coverage level 1 and a coverage which is less than the threshold 0is the coverage level 2.

The method of determining, by the UE, according to its own UE powerclass and the second access parameter information, the wireless coveragelevel may be: for the initial PRACH process of conventional power classUE: after receiving the broadcast message, the conventional power classUE acquires a wireless coverage level RSRP threshold [threshold 0,threshold 1]: determining the wireless coverage level by comparing thewireless coverage level RSRP threshold with a RSRP value measuredcurrently; a coverage in which the RSRP value is greater than or equalto the threshold 0 is coverage level 0; a coverage in which the RSRPvalue is less than the threshold 0 and greater than or equal to thethreshold 1 is coverage level 1; and a coverage in which the RSRP valueis less than the threshold 1 is coverage level 2. A minimum receivinglevel threshold selected by the cell is configured as −140 dBm, whichcan guarantee that the conventional power class UE can only reside at acell whose wireless quality is greater than −140 dBm. For the initialPRACH process of the low power class UE: after receiving the broadcastmessage, the low power class UE acquires the wireless coverage levelRSRP threshold [threshold 0, threshold 1]: determining the wirelesscoverage level by comparing wireless coverage level RSRP threshold +6 dBwith the RSRP value measured currently: a coverage in which the RSRPvalue is greater than or equal to “the threshold 0+6 dB” is the coveragelevel 0; a coverage in which the RSRP value is less than “the threshold0+6 dB”, and greater than or equal to “the threshold 1+6 dB” is thecoverage level 1 and a coverage in which the RSRP value is less than“the threshold 1+6 dB” is the coverage level 2. The 6 dB added in theabove determination is a predefined offset value, this value may beadjusted according to the actual network situation or be a wirelesscoverage level threshold deviation transmitted by an eNB to the UE bythe broadcast message. The minimum receiving level threshold selected bythe cell is configured as −140 dBm and the relevant parameter selectedby the cell is reasonably configured, enabling that the low power classUE obtains a power compensation of 6 dB in the reselection process andguaranteeing that the low power class UE can only reside at a cell whosewireless quality is greater than −140 dBm+6 dB.

On the basis of the embodiment shown in FIG. 7, after the UE triggersthe PRACH process, the UE may also transmit RRC connection informationto the base station in the PRACH process. The RRC connection informationincludes at least one of the UE power class or the downlink wirelesscoverage level of the low power class UE. The RRC connection informationincludes at least one of RRC connection request information, RRCconnection resume request information, or RRC connection reestablishmentrequest information. At least one of the UE power class or the downlinkwireless coverage level of the low power class UE included in the RRCconnection information is reported by RRC signaling or a MAC controlunit in the RRC connection information.

Two bits in the MAC control unit in the current NB-IoT system arereserved and unused. When the UE reports at least one of the UE powerclass or the downlink wireless coverage level of the low power class UEby the MAC control unit, for example, two bits may be reserved in theMAC control unit for reporting the UE power class and the wirelesscoverage level of new power class UE. The two bits have four values: 0represents the wireless coverage level 0 of the low power class UE; 1represents the wireless coverage level 1 of the low power class UE; 2represents the wireless coverage level 2 of the low power class UE and 3represents the conventional power class UE.

FIG. 7 shows that the base station broadcasts the second accessparameter information, that is, the base station transmits the secondaccess parameter information in the initial PRACH process. Moreover, thebase station may also transmit the second access parameter informationto the UE by a PDCCH order. The second access parameter informationincludes an uplink coverage level and a downlink coverage level of theUE, or the second access parameter information includes the uplinkcoverage level and the number of physical layer repetitions of the PDCCHof the UE. The base station, determines according to the downlinkcoverage level of the UE in the second access parameter information, totransmit the number of physical layer repetitions of the PDCCH to theUE, or the base station determines according to the number of physicallayer repetitions of the PDCCH in the second access parameterinformation, to transmit the number of physical layer repetitions of thePDCCH to the UE. After the UE receives the second access parameterinformation transmitted by the base station by the PDCCH order, the UEmay directly acquire the coverage level information and determine,according to the downlink coverage level in the second access parameterinformation, the number of physical layer repetitions of the PDCCHtransmitted by the base station, or determine, according to the numberof physical layer repetitions of the PDCCH in the second accessparameter information, to receive the number of physical layerrepetitions of the PDCCH transmitted by the base station.

13 bits in the PDCCH order in the current NB-IoT system are reserved andunused. When the UE reports at least one of the UE power class or thedownlink wireless coverage level of the UE by the PDCCH order, forexample, two bits may be reserved in the PDCCH order for indicating thedownlink wireless coverage level of the low power class UE. The downlinkwireless coverage level is determined based on a matching between thenumber of physical layer downlink repetitions of a PDCCH common searchspace (CSS) of the UE and the PRACH parameter. The number of physicallayer downlink repetitions of the PDCCH CSS is determined based on thenumber of historical downlink repetitions of the UE or historical reportinformation of the UE. For example, 11 bits may be reserved in the PDCCHorder for indicating the exemplary of the number of physical layerrepetitions of the PDCCH CSS of the low power class UE. The number ofphysical layer repetitions of the PDCCH CSS is determined based on thenumber of historical downlink repetitions of the UE or historical reportinformation of the UE. 4 bits may be reserved in the PDCCH order forindicating an index of the number of physical layer repetitions of thePDCCH CSS of the low power class UE.

FIG. 8 is a flowchart of a wireless resource configuration methodaccording to embodiment five of the present disclosure. As shown in FIG.8, the wireless resource configuration method in this embodimentincludes:

In step S801, a base station broadcasts third access parameterinformation. The third access parameter information includes a parameterrelated to a UE power class. The parameter related to the UE power classincludes at least one of: a wireless coverage level threshold for UEpower class, a PRACH resource or a number of physical layer repetitionsof a PRACH configured based on a wireless coverage level.

In the embodiment shown in FIG. 7, the parameters included in the secondaccess parameter information transmitted by the base station areirrelevant to the UE power class. The corresponding parameter needs tobe further measured and determined after the UE receives the secondaccess parameter information. In this embodiment, the third accessparameter information broadcast by the base station directly includesthe parameter related to the UE power class, which includes the wirelesscoverage level threshold for UE power class, the PRACH resource and thenumber of physical layer repetitions of the PRACH configured based onthe wireless coverage level. The wireless coverage level threshold forUE power class is relevant to the UE power class. After receiving thethird access parameter information, the UE may determine, according toits own UE power class, at leat one of the wireless coverage levelthreshold and a PRACH parameter corresponding to the UE power class.

In step S802, for an initial PRACH process, the UE selects the wirelesscoverage level threshold corresponding to the UE power class accordingto a matching between the UE power class and a wireless coverage levelthreshold list for UE power class in the broadcast.

In step S803, for the initial PRACH process, based on the step S802, theUE acquires, according to a comparison between a wireless qualitymeasurement value and the wireless coverage level threshold, thewireless coverage level in which the UE is currently located.

In step S804, the UE selects, according to the wireless coverage levelin which the UE is currently located as well as the PRACH resource andthe number of physical layer repetitions of the PRACH configured basedon the wireless coverage level, an available PRACH resource.

In step S805, the UE transmits PRACH information on the PRACH resourcecorresponding to the wireless coverage level in which the UE iscurrently located.

In step S806, after receiving the PRACH information, the base stationreceives the resource occupied by the PRACH information as well as thePRACH resource and the number of physical layer repetitions of the PRACHconfigured based on the wireless coverage level, and currentlydetermines the wireless coverage level of the UE, thereby currentlyacquiring the number of physical layer repetitions of the PRACH in thewireless coverage level of the UE.

In step S807, the base station performs a PRACH demodulation anddetermines transmission time of a random access response subsequentlyaccording to the number of physical layer repetitions of the PRACH.

In step S808, the base station transmits the random access response tothe UE.

The wireless coverage level RSRP threshold list configured for UE powerclass may be performed in the following manners. In this embodiment,only two UE power classes are differentiated, UE power class supportedby LTE R13 version and UE power class newly introduced by LTE R14version. The wireless coverage level threshold list respectivelycorresponds to rsrp-ThresholdsPrachInfoList-r13 and rsrp-ThresholdsPrachInfoList-r14. If the UE is the UE power class supported by LTE R13version, then rsrp-ThresholdsPrachInfoList is a value of parameterrsrp-ThresholdsPrachInfoList-r13 when determining the wireless coveragelevel; and if the UE is the low power class newly introduced by LTE R14version, rsrp-ThresholdsPrachlnfoList is a value of parameterrsrp-ThresholdsPrachInfoList-r14 when determining the wireless coveragelevel.

On the basis of the embodiment shown in FIG. 8, for example, thetransmitted third access parameter information includes informationdescribed below. The wireless coverage level threshold list ofconventional UE is configured to [−100, −120], and the wireless coveragelevel threshold list of low power class UE is configured to [−80, −100].The number of physical layer repetitions of the PRACH is configured asfollows: {wireless coverage level 0: 1 time, wireless coverage level 1:8 times, and wireless coverage level 2: 32 times}. For conventional UE1and low power class UE2 both with a same wireless quality value of 90dBm, since the wireless coverage level threshold is different, for theconventional UE1, 90 dBm is greater than a first wireless coverage levelthreshold of −100, the wireless coverage level is 0 and thecorresponding number of physical layer repetitions of the PRACH is 1;for the low power class UE2, 90 dBm is less than the first wirelesscoverage level threshold of −80 and is greater than a second threshold−100, the wireless coverage level is 1 and the corresponding number ofphysical layer repetitions of the PRACH is 8.

FIG. 9 is a flowchart of a wireless resource configuration methodaccording to embodiment six of the present disclosure. As shown in FIG.9, the wireless resource configuration method in this embodimentincludes the steps described below.

In step S901, a base station broadcasts third access parameterinformation. The third access parameter information includes a parameterrelated to a UE power class. The parameter related to the UE power classincludes: a wireless coverage level RSRP threshold list and a PRACHparameter for UE power class. The PRACH parameter for the UE power classincludes a PRACH resource and a number of physical layer repetitions ofa PRACH configured based on a UE power class and a wireless coveragelevel.

In step S902, for an initial PRACH process, the UE acquires, accordingto a comparison between a wireless quality measurement value and thewireless coverage level RSRP threshold list, the wireless coverage levelin which the UE is currently located.

In step S903, the UE selects, according to the UE power class, thewireless coverage level in which the UE is currently located as well asthe PRACH resource and the number of physical layer repetitions of thePRACH configured based on the wireless coverage level, an availablePRACH resource.

In step S904, the UE transmits PRACH information on the PRACH resourcecorresponding to the wireless coverage level in which the UE iscurrently located.

In step S905, after receiving the PRACH information, the UE receives theresource occupied by the PRACH information and determines, based on thePRACH resource and the number of physical layer repetitions of the PRACHconfigured based on the wireless coverage level, the UE power class andthe wireless coverage level of the UE.

In step S906, the base station performs a PRACH demodulation anddetermines a transmission time confirmation of a random access responsesubsequently according to the UE power class and the wireless coveragelevel of the UE.

In step S907, the base station transmits the random access response tothe UE.

In step S908, the base station performs, according to the UE power classand the wireless coverage level obtained in step S905, adaptivescheduling on a subsequent uplink and downlink resource. The resourceincludes a physical layer resource allocation and a number of physicallayer repetitions. The subsequent uplink and downlink resource includesthe random access response and a resource used for subsequent signalingand data transmission.

The PRACH resource and the number of physical layer repetitions of thePRACH configured for the UE power class may be performed in thefollowing manners. In this embodiment, only two UE power classes aredifferentiated: UE power class supported by LTE R13 version and UE powerclass introduced by LTE R14 version. The PRACH resource and the numberof physical layer repetitions of the PRACH respectively correspond tonprach-ParametersList-r13 and nprach-ParametersList-r14. If the UE isthe UE power class supported by LTE R13 version, thennprach-ParametersList is a value of parameter nprach-ParametersList-r13when determining the wireless coverage level; and if the UE is the lowpower class newly introduced by LTE R14 version, nprach-ParametersListis a value of parameter nprach-ParametersList-r14 when determining thewireless coverage level.

Furthermore, in a multi-carrier cell, the PRACH resource (including thenumber of physical layer repetitions of the PRACH) with different UEpower class may be configured on different carrier. When selecting aPRACH carrier, the UE preferably selects the PRACH resourcecorresponding to the UE power class, the selecting strategy may be, butis not limited to the following manners: the UE selects a frequencypoint carrying the PRACH resource of the UE power class, numbers in afrequency point order, and selects an available PRACH frequency pointlist of the UE. The UE calculates, based on information of a UE markerand a number of the available PRACH frequency point of the UE, a PRACHfrequency point number of the UE by a predefined rule, thereby obtainingthe PRACH frequency point of the UE. The predefined rule may be a ruledetermined based on the information of the UE marker and the number ofthe available PRACH frequency point of the UE. For example, the PRACHfrequency point number is the number of the available PRACH frequencypoint of UE ID mod.

It is assumed that a multi-frequency-point cell includes four frequencypoints capable of carrying the PRACH. Frequency point A0/A1 can onlycarry the PRACH of the conventional power class UE. Frequency pointB0/B1 can only carry the PRACH of the low power class UE. The predefinedrule is the number of the available PRACH frequency point of the UE IDmod. When selecting the PRACH, the conventional power class UE firstlyselects a frequency point list {A0, A1} capable of carrying the PRACH ofthe conventional power class UE, then selects, based on the UE marker,the PRACH frequency point in the predefined rule. When the UE marker isan even number, frequency point A0 (even number mod 2=0) is selected;and when the UE marker is an odd number, frequency point Al (even numbermod 2=1) is selected. When selecting the PRACH, the low power class UEfirstly selects a frequency point list {B0, B 1 } capable of carryingthe PRACH of the low power class UE, then selects, based on the UEmarker, the PRACH frequency point in the predefined rule. When the UEmarker is the even number, frequency point B0 (even number mod 2=0) isselected; and when the UE marker is the odd number, frequency point B1(even number mod 2=1) is selected.

In addition, the embodiments in FIGS. 8 and 9 may be combined. That is,the third access parameter information broadcast by the base stationincludes the wireless coverage level RSRP threshold list configured forUE power class and the PRACH parameter for the UE power class. The PRACHparameter for the UE power class includes the PRACH resource and thenumber of physical layer repetitions of the PRACH configured based onthe UE power class and the wireless coverage level, which is equal touse the wireless coverage level RSRP threshold list configured for UEpower class as well as the PRACH resource and the number of physicallayer repetitions of the PRACH configured based on the UE power classand the wireless coverage level at the same time, making the wirelessparameter configuration more flexible.

After combining the embodiments shown in FIGS. 8 and 9, the wirelessparameter configuration method may be further described according to thefollowing embodiment: conventional power class UE (20 dBm) is configuredwith two wireless coverage level RSRP thresholds [threshold 0(−120 dBm),threshold 1(−130 dBm)]. For the conventional power class UE, a coveragein which the RSRP value is greater than or equal to the threshold 0 iscoverage level 0; a coverage in which the RSRP value is less than thethreshold 0 and greater than or equal to the threshold 1 is coveragelevel 1; and a coverage in which the RSRP value is less than thethreshold 1 is coverage level 2. The low power class UE (14 dBm) isconfigured with three wireless coverage level RSRP thresholds [threshold0(−114 dBm), threshold 1(−124 dBm), threshold 2(−134 dBm)]. For the lowpower class UE: the coverage in which the RSRP value is greater than orequal to the threshold 0 is coverage level 0; the coverage in which theRSRP value is less than the threshold 0 and greater than or equal to thethreshold 1 is coverage level 1; and a coverage in which the RSRP valueis less than the threshold 1, and greater than or equal to the threshold2 is coverage level 2, a coverage in which the RSRP value is less thanthe threshold 2 is coverage level 3. The resource configured for thecoverage level 0, the coverage level 1 and the coverage level 2 may beused by the conventional power class UE (20 dBm) and the low power classUE (14 dBm). The resource configured for the coverage level 3 may onlybe used by the low power class UE (14 dBm).

FIG. 10 is a flowchart of a wireless resource configuration methodaccording to embodiment seven of the present disclosure. As shown inFIG. 10, the wireless resource configuration method in this embodimentincludes:

In step S1001, a base station broadcasts third access parameterinformation, the third access parameter information includes a parameterrelated to a UE power class, the parameter related to the UE power classincludes at least one of: a wireless coverage level threshold for UEpower class, a PRACH parameter for the UE power class, or a maximumnumber of physical layer repetitions of the PDCCH of bearer pagingscheduling information for the UE power class. The maximum number ofphysical layer repetitions of the PDCCH of the bearer paging schedulinginformation for the UE power class is used for indicating a maximumnumber of physical layer repetitions of the PDCCH of a paging message ofdifferent UE power class.

In step S1002, the base station determines, based on the UE power class,the maximum number of physical layer repetitions of the PDCCH of a UEbearer paging message.

In step S1003, the base station determines, based on the power class,the maximum number of physical layer repetitions of the PDCCH of the UEbearer paging message, thereby determining a paging search space. The UEdetermines according to its own UE power class information whenperforming a paging reception. The conventional power class UEdetermines the paging search space and performs the paging receptionaccording to the maximum number of physical layer repetitions of thePDCCH of the paging message. The low power class UE determines thepaging search space and performs the paging reception according to themaximum number of physical layer repetitions of the PDCCH of the pagingmessage of the low power class UE.

In step S1004, a mobility management entity transmits the paging messageto the base station, and carries the UE power class information.

The method of acquiring the UE power class by the MME may be a valueextension of reporting the power class by the UE to the MME in theRel-13 NB-IoT. The Rel-13 NB-IoT only currently reports whether it is apower class of 20 dBm. If the Rel-13 NB-IoT does not report, it isconsidered as a power class of 23 dBm. When introducing a power class of14 dBm, in the exemplary manner, the Rel-13 NB-IoT may report whether itis the power class of 20 dBm or the power class of 14 dBm. If the Rel-13NB-IoT does not report, it is considered as the power class of 23 dBm.

In step S1005, the base station transmits the paging message to the UE.The UE receives and transmits the paging based on the maximum number ofphysical layer repetitions of the PDCCH of the bearer paging messagedetermined by the power class.

The maximum number of physical layer repetitions of the PDCCH of thepaging message configured for the UE power class may be performed in thefollowing manners. In this embodiment, only two UE power classes aredifferentiated: UE power class supported by LTE R13 version and UE powerclass introduced by LTE R14 version. The maximum number of physicallayer repetitions of the PDCCH of the paging message respectivelycorresponds to npdcch-NumRepetitionPaging-r13 andnpdcch-NumRepetitionPaging-r14. If the UE is the UE power classsupported by LTE R13 version, the maximum number of physical layerrepetitions of the PDCCH of the paging message is the value of parameternpdcch-NumRepetitionPaging-r13. If the UE is low power class newlyintroduced by LTE R14 version, the maximum number of physical layerrepetitions of the PDCCH of the paging message is the value of parameternpdcch-NumRepetitionPaging-r14.

If theindication element exists in the message, the UE is the low power classUE; otherwise, the UE is conventional power class UE. Alternatively, theindication element may also be the specific value of the UE power class(such as power class 3, power class 5, and power class newly added byR14), or a value reporting the combination of UE power class indicationand the downlink wireless coverage level of the low power class UE, suchas 0 represents wireless coverage level 0 of the low power class UE, 1represents wireless coverage level 1 of the low power class UE, 2represents wireless coverage level 2 of the low power class UE and 3represents non-low-power-class-UE.
